To all whom it may concern;

Be it known that we, WILBUR R. CORBIN and WILLIAM K. HENRY, of New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Hinges for Double-Acting Doors; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others roskilled in the art towhich it appertains to make and use the same.

Our invention relates toan improvement in hinges for double-acting doors and is a division of application Serial No. 725,505, filed by [5 us July 29, 1899.

The ob ect 0t our lnvention is to provide improved means for pivotally supporting a double-acting door in its frame; and it consists in the details of construction and combinations of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View in elevation of a door embodying our invention. Fig. 2 is a plan view of the door.

2 5 Fig. 3 is a view in vertical section through the upper hinge of the door, and Fig. 4 is a similar View through the lower hinge.

A represents the door, adapted to swing in either direction and preferably with a convex rear edge, as shown in Fig. 2. This door is supported at its top and bottom by the hinges, the lower of which is composed of two sections B and B. The section B of the lower hinge comprises a plate having screw-holes therein 5 for its attachment to the sill, at one end of the latter, and is provided at is outer end with an enlarged circular section a, the downwardlyprojecting portion of which rests within a recess formed in the sill. The upper face of 0 this circular portion of section B of the hinge is recessed, the latter being encircled by the circular rib 2). Located within the recess is the steel block 0, having a groove in which the steel balls at rest and move. The upper section B is U shape in horizontal cross-section, so as to embrace the lower edge of the door, and is closed atits bottom, so as to form a seat for the inner lower edge of the door and thus sustain a portion of the strain which would otherwise fall on the screws employed so for securing section B to the door. This section B of the lower hinge is provided near its rear end with a thickenedcircular portion 6, having a recess adapted to receive the steel block 0', the latter being grooved and, to-' gether with the groove in block 0, forming a raceway for the balls (1. The upper section or pivotal butt B is also provided'on' its lower face with the depending circular rib b,which latter overlaps the rib b and assists in preventing lateral displacement of the two sections 13 and B of the lower hinge. The two sections are further connected by the pivotpin D, which latter passes through openings in sections 13 and B and through openings in the intermediate blocks 0 and c. The side of the upper section B is provided with screwholes for securing the section in place.

The upper hinge is composed of two sections, one of which comprises a flat plate 0, provided at its rear end with a depending cam-flange f, the latter being of an oval shape in plan and having a V-shaped cut-away portion, the apex of the V-shaped cut-away portion being on a line with the longitudinal cen- 'ter of the door when the latter is closed. De-

pending from the plate 0 and eccentric to the flange f is the pivot-pin g, which latter enters an opening formed in the top plate 0 of the upper hinge.

edge of which is concentric with the axis of the pin and rests within a short circular rib h, formed on the top plate of the section 0 of the top hinge. The section G of the hinge is also U shape in cross-section and closed at its top and is provided on its sides with screwholes for its attachment to the rear top edge of the door. That portion of the section C of the upper hinge immediately below the flange f is made solid to form an extended bearing for the pivot-pin g and also a seat for the spiral spring E, the upper end of which bears against the inner end of the weatherstrip F. This weather-strip is preferably 5 made of thin sheet metal and is seated in a The lower edge of the flange f 80 is provided with a slight flange f, the outer" slot or kerf extending from the outer edge of the top of the door back to a point near the pivot-bolt g, the slot or kerf being deep enough to receive and conceal the weather-stri p. The

inner edge of the weather-strip, as before stated, rests on the spring and is provided near its outer end with an inclined slot through which a pin securedto the door passes. Thus it will be seen that when the weather-strip is moved longitudinally the outer end rises or falls. The upper end of the weather-strip is provided near its inner end with a notch 1 adapted to receive the cam-flange f. The

apex of the V-shaped "cut-away portion of the cam-flange is, as before stated, in line with the weather-strip or center of the door. Hence it will be seen that when the door is in its closed position the weather-strip is projectedby the spring E and flange F to its highest position and thus efiectually closesthe space between the top of the door and-the lower fac of the easement. When the door is pushed open, the inclines of the-flange f operate to depress the inner end of the weather-strip, while the ovalsh'ape of thevflange 1 moves the weather-str-ip-longitudinally and thus lowers the outer end of the weather-strip. This movement takes place whenthe door is opened in either direction, and the weather-strip-rises as the door comes to its normal position.

We makeno claim in this application to the weather-strip-or to the manner of supporting or actuating it, as such features 'formthe subject of application Serial No 725,505, filed by us July 29, 1899. I

It is eviden-t that numerous slight changes might be resorted to in the relative arrangement of parts herein shown and described without departing from the spirit and scope of our invention. Hence we would have it understood that we do not wish to confine ourselves to the exact construction shown and described; but,

Havingfully described our invention, what we claim as new, and desire to secure by Letters Patent, is. v i

p 1. A hinge composed of two sections one of which is adapted to be secured to the sill and the other tothe door, each section having a flange adapted to-over-lap the flange of the other section and a seat or recess within the space bounded by the flange, ahardened plate having a raceway located in each seat or recess "and a pin passing through both sections of the hinge and the harden'edplates.

, 2. The combination with a double-acting door, of hinges eachcomprisin g two parts one part of each hinge being securedto the doorframe, while the other part of each is U shape in cross-section and is closed at its outerend,

the said parts having overlappingflanges and a'pin connecting the two parts of each hinge. 'In testimony whereof we have signed this specification in the presence of twosubscribing witnesses.
